摘要:
 海上油田常因油水井近井地带污染、筛管堵塞、低孔低渗造成油井低产低效。可控冲击波增透技术是一种新型物理法解堵增透技术，以高功率电脉冲与放电等离子体为基础，将含能材料包裹在金属丝周围，利用金属丝电爆炸产生等离子体驱动含能材料释能解堵。通过改变含能材料配方优化可控冲击波波形，实现高渗储层解堵、中/低渗储层增透。通过地面打靶试验验证，该技术适用于裸眼、套管射孔、筛管、砾石充填等多种完井方式；冲击30次后套管、筛管无损伤、无扩径、无穿孔，筛管挡砂精度检测后符合应用标准；不影响井下封隔器密封性能。该技术环保节能、安全可控、不伤害储层，可与现有增产措施形成技术优势互补，发展成为一种高效低成本的解堵增透技术。
Abstract:
Offshore oilfields often have performance of low production and low efficiency due to damage near wellbore, screen blockage, low porosity and low permeability. Permeability improving technology with controllable shockwaves is a new kind of plug removal technology by physical method. On the basis of highpower electrical impulses and discharge plasma, this technology wraps the energycontaining material around the metal wire, and use plasma, which is generated by electrical explosion of the metal wire, to drive energycontaining material to release energy used for plug removal. Waveform of controllable waves can be optimized by changing the formula of the energycontaining material, realizing plug removal in high permeability reservoir and permeability improvement in medium/low permeability reservoir. After ground firing test, the technology is applicable to many completion styles such as openhole completion, perforated casing completion, screen completion, gravel packing completion and so on. After 30 times of impact, there is no damage, no expansion, and no perforation on the casing and screen, and the sand control precision of screen meets the application standard. The shockwave does not affect sealing performance of well packer. The technology is environmentally friendly, energysaving, safe and controllable, and does not harm the reservoir. It can complement with the existing stimulation measures to develop into an efficient and lowcost technology to improve permeability and remove plugs.
